摘要: The invention relates to a device for protecting against the overspeed of free turbine (6) engine which comprises gas generator including at least one compressor (1), combustion chamber (3), linked (4) and system controlling fuel injected into said chamber, gases produced by being sent (6), torque-measuring means (12) supported an output shaft (8, 11) mechanically coupled turbine, signal-processing unit capable transmitting order control reduce flow rate in event it is detected that torque drops below set value, wherein measurement used triggering reduction carried out during rotation corresponding fraction revolution 11).
